Abstract

An analysis of local flame area was performed using DNS databases of turbulent premixed flames with different density ratios and with different Lewis numbers. A local flame surface at a prescribed progress variable was identified as a local three-dimensional polygon. The polygon was divided into some triangles and local flame area was evaluated. The turbulent burning velocity was evaluated using the ratio of the area of turbulent flame to that of planar flame and compared with the turbulent burning velocity obtained by the reaction rate.
